To all whom it may cmwern.-

Be it known that I, FRANCIS MARION SAR- GENT, a citizen of the United States of America, and a resident of Washington, county of Washington, and State of Pennsylvania., have invented certain new and useful Imrovement's in Devices for liasteninov Sewingilachines in Wagons, of which the rfollowing is a specification.

My invention relates to new and useful improvenients in devices for fastening sewingmachines to wagon-bodies and it consists in the particular construction, arrangement, and combination of parts, which will hereinafterbe fully described.

The object of the invention is to provide a simple and cheap fastening device whereby sewing-machines may .he readily clamped in place in a wagon.

A further object is to provide a fastening `device for rigidly holding sewing-machines in wagon-bodies which is convenient to handle and which may be quickly applied and removed.

In describing the inventioniin detail reference is herein'had to the accompanving draw- -ings, forming a part of this specification, in

Figure 1 is a side elevation of the inven-f tion, showing a. section of the bottom of a i' wagon bed or body with the hook in engagement with the rod. Fig. 2 is a top plan view 5 of the invention, andFig. 3 is a bottompla view of a portion of the wagon-bed'.

Referring to said drawings, in which like reference numerals designate like parts throughout the several views, 1 indicatesa vthreaded stem having an integral hook 2 on. 2 its lower and and preferably having a loop-- handle 3 'on its upper end. Slidably mounted on said stem 1 is a clamping member 4, which may be of any suitable form. In the' 'present instance said clampin member is l shown'as consisting of a longitu( inal bar, the

same being adapted for resting upon the to 'f of a sewing-machine trcadle, through whic i the lowcrrend of said stem is vertically pro- Aljectech said stem being passed through one 'of the ordinary openings or apertures in the` fifi-5o treadle. 1.- In the bottom 5 of the wagon-bed in which .lthe sewing-machine is to be carried is a shortv #flo 'tudinal slot 6, and secured, by means of nai s er screws 7, on said bottom 5, preferably on the unde'r side, and extending transversely across, said slot, as shown, is a rod 8, which 1s mounted on said stem, a follower mounted on said stem above the cross-bar, and hook`.

adapted to he engaged by the hook 2, which Y 1s projected through said slot 6.

Having projected the lower end of the stem 1 through the treadle and through the slot 6 6o in adjusting the fastening device in position the upper end of the stem l or the handle 3 is grasped, and the device is thereby held upraised, with the hook 2A in interlocking engagement with the rod 8. The bar 4 is then 65 arranged to'lie ytransversely across the sewing-machine treadle, and a follower comprising a wheel Qf, having an interiorlythreaded hub 10, which is mounted on said stem above said bar 4, is turned down over je the threadsof the stem until the lower end the said hub 10 binds upon said bar, where-\ upon the hook 2 is held firmly int'erlocked with the rod 8, and the sewing-machine is rigidly clamped in place. A

When it is desired to release the sewing- Inachine, the wheel 9 is turned backward to release the bar 4 from binding engagement with the treadle and to allow the book to disengage from the rod 8, when the stem carrv- 8o infr said hook, bar, and wheel may be readily U removed.

The wheel 9 is preferably made heavy, so that a quick swing of the Wheel by hand causes said wheel to travel a considerable dis- '85 tance over the threads of the stem, thus facilitating the ready adjustment of the device.

As is obvious, an adjusting-nut might be employed instead ot the wzbeel. However, owing to the comparative ease and rapidity 9o with which the adjustment may he effected the wheel is deemed greatly preferable.

An ordinary staple driven in the bottom of the wagon-bed might he employed to serve the purpose of the rod S; but such staple 95 would be more or less lic-ble to work loose.

Hence the rod extended transversely of n. slot 4 provided in the bottom, as hcrcinbefQrc described, is preferred. Having thus described my invention, what roo I claim as new, and desire to secure by Let- 1 ters Patent, is v 1. I'n a device for fastening sewing-macliines in wagons. a iongitudmal threaded stem, a hook on the lower end of the stem, a :o5 horizontal cross-bar centrallv and slidably g! enga 'ng means carried by the wa embody. ,1 2. n a. device of the character escribed, -rro the combination with the bottom of a wagon- 5 lower on'said stem above said cross-bar whereby a ready adjustment. may ,be secured'. 3. In a device of the character describe-d,

the combination with the bottom of a wagon= xo bed having hook-engaging means mounted "therein, of a threaded stem adapted for rojecting vertically through a sewing-mac iine .treadle, a hook on the lower end of said stem for interlocking engagement with said hookx5-engaging means` a hand-grasp provided on the u .per end of said stem, a clamping member slridable upon said stem and adapted for resting upon said treadle, and a hand-Wheel follower in threaded engagement with said zo stern above said clam ing member.

4. In a device of tie character described, the combination with a Waden-bed having a slot in its bottom, of a rod secured to said bottom and extending transversely across 2; said slot. a threaded stem having a hook upon its lower end for engagement with said rod, said stem being adapted for' insertion through the treadle of a sewing-machine, a slidable cross-bar centrally mounted on said 3o stem, and means carried by said stem wherebysaid barmay be clamped upon said treadle.

5. In means for fastening sewing-machines in wagons, a wagon-bottom having a slot therein, a rod extended transversely 35 across said slot and attached to the wagonbottom, a longitudinal threaded stern, a hook on the lower end of said stem, a bar said bar.

slidably mounted on saidstem, and a threaded hand-wheel follower on said stem abev'e In a fastening device for sewing-Inai-x chines, the combination with a wagon-body havinga slot in its betteln, of a rod secured to said *bottom and extending transversely across said slot, a threaded stem having a hook uponits lower endior engagement with said rod, said stein being adaated for insertion through an aperture in the treadle of a sewing-machine, a clamping member slidable upon said stem and adapted for resting upon said treadle, and a follower in threaded en gagement with said stem above said clamping member whereby the latter is caused to firmly bind upon said treadle, said follower comprising a heavy Wheel having an interiorly-threaded hub.

7. Ina device of the character described, the combination with a Wagon-body, of a longitudinal threaded stem, a hook carried by the lower end of said stem, a handle on the upper end of said stem. a bar slidable upon said stem, a hand-wheel having an interiorlythreaded hub in threaded engagement with said stem above said bar, and a rod, adapted to be engaged by said hool, secured on the under side of the bottom of said wagon-body and extendingv transversely across a slot provided in said bottom.

In testimony whereof I aflix my signature in presence of two subscribing witnesses.
